HARVESTER-RAKE.

SPECIFICATION' forming part of lLetters Patent No. 313,135, dated March 3, 1885.

pplication filed March 16, i883. (No model.)

To all whom it may concern:

Be it known that I, Mllizsn VAN Mrvrrnson, of Milwaukee, in the county of Milwaukee and State of Wisconsin, have invented certain new .and useful Improvements in Harvester-Rakes; and I do hereby declare that the following is a full, clear, and exact description thereof.

My invention consists in certain peculiarities of construction, as will be more fully set forth herein-after.

In the drawings, Figure l is a perspective View of the rake post or standard. Fig. 2 `is a perspective view of the rake-plate and attachments. Fig. 3 is a perspective View of the bevel rake-wheel on a reduced scale. Fig. 4 is a perspective view of the cap or cam. Fig. 5 is a sectional view of a portion of the rakerail. Fig. 6 is a plan view of the rake-trip. Figs. 7 and S are vertical sectional views of said trip. Fig. 9 is aperspective view of the rake, showing two of the rakes in position'. Fig. l0 is a perspective view of one of the rake-arms. Fig. 11 is a perspective view of one of the rake-arm sleeves with the rigid dog attached. Fig. 12 is a perspective view of a rake-arm sleeve with movable dog attached; and Fi g. 13 is a vertical section,on an enlarged scale, of said dog.

M is a hollow post or standard of general conical form, and adapted to be securely fastened by means of its flanged base to the platform of a harvesting-machine. The upper part of this post is provided with a circular flange, m, having two projecting4 lugs', mf, exactly opposite each other, while the top of the cone extends a short distance above the iiange, and is truncated, as shown in the detail view, Fig. l, the whole being cast in one piece.

M is a plate of irregular shape, provided with a central hole, and adapted to tit over the top of the post M, the under side of said plate being provided with depressions to receive the flange m and its lugs m', and thus be securely locked thereon. This plate h' has a downward and outward projecting arm, m', ending in a box or housing, Mwhich receives one end ofthe rake rail or cam M3. This rail is preferably a rigid curved bar, theinner end of which rests within the housing M2, and is the slots mama, through which pass the bolts m4 m4, around which are the coiled springs M4 M4, one above and the other below the said rail, as shown.

From one side of the plate M and from a strengtheninglug, a, cast therewith, there depends a ilange, N, also integral with the plate. and which serves as the support of a beveled pinion, N', secured by means of thimble and bolt (not shown) to said flange; and the pinion is provided with ears n n', for attachment .to one end of a tumbling-shaft (not shown) bv means of ordinary knuckles, rings, and pins, the said tumbling -shaft being constructed with a clutch near its other end, where it is connected by knuckles, rings, and pins to the inner end ofthe axle ofthe maindriivewheel, all aswell known in this class of machines. Around the central opening in the plate M rises a collar, n2, the upper. part of which is of reduced external diameter, so as to form a circular shoulder, and this reduced part is provided with the notches n n3 to receive the rake cap or cam, as hereinafter described..

O is a horizontal bevel rake-wheel, having a central opening to enable it to be placed over the collar ir of the plate M and rest on the plate M', and its cogs o mesh with the pinion N, just described. The central opening of this wheel is encircled by a vertical collar, o', from which extend the ears o o?, to which the rake-arms are pivoted, all the, parts of this wheel O being integral.

P is the cap or cam of the rake-standard, of the general shape shownin Fig. ll. Its bottom `is provided with an opening, and there has two inward proiections,p,opposite each other, which, after the crown-wheel O has been mounted on the collar u2 of the plate M, will fit into the notches a of said collar. Vhen all these parts have been put together, as shown in Fig. 9, a bolt is passed up through all from the under side of the platform, and a nut is screwed on this bolt above a washer in the cam I), thus securing allf'ffirmly together.

M5 is a rake-guide, bolted, as shown, to the projecting portions m2 m5 of the plate 5 and m is a continuation of the projection m",.pass ing above the trip, and designed as a Stop to 5o bent as shown in Fig. 5, and provided with limit the upward movement of said trip. The 10o projection m5 of the main plate Mhas a nearlyradial straight edge, and. opposite to this is the nearly-radial straight edge of another projection, m", of the said plate M', and between these edges the trip Qis located. This tripis supported by the trip-holder Q,which isfast-l ened to the under side of the projections m5 m7 of the plate M by bolts ms m8 passing through holes g q in said holder Q and through slots mi in the said projections, whereby the holder and trip may be adjusted in or out from the frame M. This holder is provided with ears q2 @which are provided with holes to receive avshaft or pivot-pin, g3, and the said holder has also cast therewith the curved guides q* qt. The trip Q has two backward-extending'arms, q q, which have each a slot, g5, through which the pivot g3 passes, and tnese arms have the nipples g cast thereon, which nipples are adapted to move between the curved guides g4 qt. At the rear or inner end of the trip Q the arms q q are united by a solid plate, q, provided with a nipple, g8, and the under side of the plate IVI is provided with a corresponding nipple, Q9, and between these .two issustained a stiff coiled spring, Q2. From the under side of the trip-holder Q there depends a lug, qm, to which is pivoted a bell-crank, Q3, the short arm of which bears against the under side of the part ql of the trip, and when the bellcrank is pulled by a trip-wire, qu, attached to the pin qu at the end of the long arm of said bell-crank the said part ql is forced upward against the force of the spring Q2, and the front end of said trip is thereby forced downward and forward. The other end of this trip-wire qu is connected to a lever (not shown) of ordinary construction within reach of the drivers foot.

The rake-arms consist of round steel rods R,

' cast within the metal shanks R', which latter are provided with the ears r r, which fit between the ears o2 o2 on the rake-wheel O, and are secured thereto by bolts passing vthrough holes in all these ears. The end of the shank R farthest from the ears r is provided with the vertical lug r2, the stop r3, and the groove r4.

S is the rake-arm sleeve, which is cast with plates s sf above and below, the plate shaving the hole s2 andy slot s, for attachment of the rake-Slat U, while the lower plate, s', has the slot s* in one end, and at the other end said plate is double, forming the housing S for the dog T or T. When this sleeve has been pushed onto the rod R, the spring R2 is slipped on the rod, and then a washer, and then these parts are all secured together by a pin, r, driven through a hole near the extreme outer end of the said rod R.

In Fig. 9 I have shown only two rake-arms connected by the link R, the ends of which link are pivoted in the lugs r2, already named; but it will be understood that in practice I use four rake-arms, the sleeves of three of which are furnished with the dogs T, (shown in Fig.V 11,) whilethe sleeve of the fourth rakearm (being the one that rakes automatically) is furnished with the dog T. (Shown in Figs. 12 and 13.) The dog T is a simple tongue or plate of metal, preferably independent of the housing S', and sustained rigidly therein by a bolt, as shown; but the dog T. is of more complicated construction, and consists of the shank t', the projecting end t2 of which is of less depth than said shank, and said shank has a downward projection, t3, provided with a central vertical recess, t, the outer edge of which is provided with dovetailed or beveled grooves, as shown at t5.

T2 is a thumbpiece pivoted within said recess, and having a spring, T6, attached to its upper end, and located between said thumbpiece and the rear wall of said recess t4. The front of this thumb-piece bears a pin, t7, at about its center, and this pin (when the parts are in the position shown in the drawings) fits within a groove or mortise, te, in the dog block T3, the inner edges of the vertical sides of which block are beveled to form a dovetail to tit within the vertical grooves t5, already described. In this position the trip Q will pass between the projection 152 and the block T3 without effect; but if it is desired to make the dog T operate like the dogs T it is only necessary to press back the thumb-piece T2 against the force of the spring t and push the block T3 up against the under side of the projection t2, (as shown in dotted lines in Fig. 13,) when, by releasing the thumb-piece, the spring t will force it out again, and then the pin il will rest underneath and support the block T3, thereby making a' solid dog of it.

V is a wooden tapered beam, which forms the top of the rake, through which the teeth 'u v are inserted. A boa-rd, V, is placed on these teeth, extending the entire length of the rake, and securely fastened to the said beam and to the teeth, and a metal strengtheningstrap, e', covers the point of junction `of the beam and board. The inner end of the rakebeam V is pivoted on the bolt o2, which secures the dog within the housing S of the rake-arm sleeve, and another bolt, e, passes throughV the slot s4 in said sleeve and through the beam, by means of which the said rake- IOO IIO

beam is adjusted up or down. A brace, V2,

extends from the said beam to a bolt, e, passing through a slot in this end of the brace, then through the slot s3 in the rake-arm sleeve, and ,thence through ahole in the rake-Slat U, already described, whereby the described adj ustment is made possible, and the outer ends (not shown) of the rake-Slat U and tooth-beam V are braced together in the ordinary manner.

The operation of my rake and trip is substantially as follows: Power is communicated to the pinion N', through the described tumbling-shaft, from the axle of the drive-wheel of the harvester, (not shown,) and this pinion turns the rake-wheel O, and thus revolves the rake-arms attached thereto. The shanks R bear against and are guided by the edge of the IZO cam or cap I), the opposite rakes of each pair being united by the links Rt, so that one rake will be going down as the other is rising in each pair.

In the normal position of my device three of the rakes act simply as reel-beaters. The raking operation is performed by the fourth rake. As the armof each of the three rakes first named, in its journey round the cam P, is forced down upon the guide M5, its dog T, which is normally within the groove r* of the shank It', will encounter the front of the trip Q, and will thus be forced out of said groove, the sleeve S being pushed outward on the rod R against the force of the spring R2, and when the rake-sleeve is released from the shank of the rake-arm said sleeve will come in contact with the rail or cam M3, and will roll or turn as far as allowed by the stop r3, so as torest horizontally on said rail, and continue in this position while moving over the platform (the rake not disturbing the cut grain thereon) until the end of the rail is reached, and then the weight of the rakebeam V and attachments will cause these parts to assume their normal vertical position, and the spring R2 will force the sleeve S back against the shank R of the rake-arm, and the dog T will enter the groove r* again, and remain rigidly therein until the trip Q is again encountered in the next revolution of the rake-head. But when the fourth rake approaches the trip Q the latter will pass, as already stated, between the projection t2 and block T3 ofthe dog Twithout moving the sleeve S, and hence as the teeth of the rake will thus remain vertical they will sweep the grain off the platform, ready for binding, and by reason of the springs M4 M4, surrounding the bolts m4E mL in the housing M2, and the slots m3 m3 in the end of the rail M3, the said rail may be forced downward under the pressure of the edge of the sleeve of said fourth rake, and hence allow the vertical teeth to nearly or quite touch the platform, and thus insure that no grain be left thereon in the continued revolution of said rake. lVhen the grain is so thin that there would not be sufficient on the platform to form a proper sized gavel with every revolution of the said fourth rake, or where (as in turning a corner) it is desirable to carry the cut grain some distance before raking` it off, the driver can prevent this fourth rake from raking by drawing on the trip-wire g, attached to the liell-crank Q, (which, as stated, may be done by an ordinary foot-lever, if desired,) when the front of the trip Q will be immediately depressed and thrown forward by the action of the parts shown in Figs. 7 and 8, and already described, and the said trip will then bear against the dog-block T3 of the dog T and force the sleeve S, to which this dog is rigidly attached, away from the shank R", unlocking the projection t of the dog T from the groove rand permitting this rake to turn and ride on the rail M3, exactly like the other rakes. If the pressure on the bell-crank is now released, the spring Q2 will restore the trip to its normal position, and there will be no raking off until this fourth rake has made another complete revolution; but if it is de- Y sired to rake off before this occurs, or cause any one of therakes to act, the driver, by again drawing on the tripwire q, will cause the front of the trip to be lowered, and it will pass under the next rigid dog, T, wit-hout freeing it from the groove in its rakelarin shank, and hence the rake will at once rake off the grain as it sweeps over the platform.

\Vhenever it is desired to size all the gavels, (as in fields where the grain is very uneven or either too high or too heavy to make proper-sized bundles by raking off with every fourth rake,) the block T3 of the dog T can be pushed up (as already described,andshown in dotted lines in Fig. 13) against the under side of the projection t2, and rigidly held in such position by means of the pin t7, and then the dogs in all the rake-arms will be exactly alike, and it will be necessary to draw on the trip-wire q every time it is desired to rake off, and thus there will be no automatic raking, but it will be wholly under the control of the driver, and may be as frequent or seldom as the accumulation of cut grain on the platform renders desirable.

Having thus described myiuvention, what I claim as new, and desire to secure byLetters Patent, is

1. In a harvesting-machine, the combination, with the platform and rake, of the rakepost M, plate M, having projection mi, provided with the housing M2, the yielding curved and bent rake-rail M3, having slots m3 m3 in its inner end, the bolts m* m4, securing said rail within said housing,and the coiled springs M4 M4 around said bolts, and located, respectively, above and below said rail, substantially as set forth.
